Description

  The present invention can impart an excellent texture to a printed fabric without generating harmful formaldehyde, can impart high washing resistance and friction resistance to the printed portion, and further overlays a dye printing agent on the fabric. The present invention relates to a pigment printing agent capable of imparting high washing resistance to a printed part and a fabric using the same.

  Conventionally, a binder resin of a pigment printing agent is a heavy resin using a polymerizable monomer having a reactive functional group such as N-methylol (meth) acrylamide in order to impart washing resistance, friction resistance, and the like. Coalescence was used. Since this polymer has a reactive functional group, high crosslinking resistance and friction resistance can be imparted by the crosslinking reaction of the functional group, but there is a problem that harmful formaldehyde is generated during the crosslinking reaction. there were.

  As a method for solving the above-mentioned problem of formaldehyde, it has been proposed to perform a cross-linking reaction with something other than N-methylol (meth) acrylamide. For example, a cross-linking agent such as an oxazoline compound or a blocked isocyanate compound may be used. Attempts have been made (for example, see Patent Document 1). However, pigment printing agents containing these cross-linking agents can sufficiently impart excellent texture to the fabric and high washing resistance, friction resistance, etc. to the printed part when titanium oxide is used as the pigment. There wasn't.

  Further, in the case of a conventional pigment printing agent, after printing on a fabric and further printing a dye printing agent thereon, or after printing a dye printing agent and further printing a pigment printing agent thereon. In the case of printing, there is also a problem that the washing resistance of a printing portion where the pigment and the dye overlap (hereinafter abbreviated as “dye heavy color portion”) is lowered.

  Therefore, an excellent texture can be imparted to the printed fabric without generating harmful formaldehyde, high washing resistance and friction resistance can be imparted to the printed portion, and high water resistance can be imparted to the dye-heavy color portion. There has been a need for pigment printing agents that can be applied.
